IMPROVEMENT IN ADJUSTABLE PlPE-TONGS.

Specification forming part of Letters Patent No. 134,207, dated December24, 1872.

To all whom it may concern:

Be it known that 1, WILLIAM KEARNEY,

of Belleville, in the county of Essex and State of New Jersey, haveinvented a new and useful Improvement in Adjustable Pipe-Tongs,

of which the following is a specification:

Figure 1 is a side view of my improved pipetongs, part being broken awayto show the construction. Fig. 2 is a detail section of the same takenthrough the line 00 on, Fig. 1. v

Similar letters of reference indicate corresponding parts.

My invention relates to improvement in pipe-tongs, of the class in whichone jaw is made adjustable by means of a screw, but is more particularlya modification of a device described in the patent of H. N. Smade, datedAugust 29, 1871. The object of my invention is to provide an adjustablejaw which shall be capable of adapting itself, within moderate limits,to the object to be'seized or held, and of being readily adjusted tovarious positions, while the construction and arrangement shall besimple and inexpensive.

A and B are the handles, which are pivoted to each other in the ordinarymanner. Upon the forward end of one of the handles, as A, is formed ajaw, O, which is curved inward and is made smooth upon its inner side.

The

inner side of the end part of the jaw G is made straight or nearly so,and at right angles, or nearly at right angles, with the length of thetongs, as shown in Fig. 1. In the end of the other arm or handle, as B,is formed a screwhole to receive the screw D, to the head of which ishinged, as shown in Figs. 1 and 2, the other jaw F, upon the end ofwhich is formed a face curved nearly in the arc of a circle and havingteeth formed upon it, as shown in Fig. 1. By this construction the jaw Ewill adjust itself to the pipe or other object to be turned so as tograsp it firmly. The screw D enables the jaw E to be adjusted accordingto the size of the pipe or other object to be grasped and turned bysimply turning it in one or the other direction.

Havingthus described m yinvention, I claim as new and desire to secureby Letters Patent- As the improvement described, the combination, withthe hooked jaw (J, of the jaw E,

hinged to the screw D, whose stem enters a socket in the end of thehandle or lever B, all as shown and described.
